A protective cover for fragile boat bumpers includes two sheets of relatively thin rubber having a sheet of criss-crossing fibers therebetween, the two rubber sheets being fused to each other. The cover is initially formed from a blank of sheet stock comprised of two flat panels and a flange or wing extending from one of said flat panels so that when said flange or wing is overlapped with a marginal portion of the other of such panels and bonded thereto, a relatively flat tubular body is formed with a passage extending therethrough. The body has a pair of flaps hingedly connected to each end thereof so that the protective cover can be pulled downwardly over a boat bumper so as to protect the foamed sleeve of which the bumper is comprised from impact forces that would break and otherwise damage the relatively fragile foamed plastic, usually polystyrene.
